Hi, I am looking for best spatial discretization scheme for following dimensionless parameters:
Re: 6.0E-5 - 0.6 Pr: 5.0E+7 - 1.5E+4 Pe: 3.0E+3 - 2.5E+3 Ra: 25E+1 - 3.0E+5 These are valid for very high viscous flows at high temperature range(1200K-1700K). My aim is to solve instability problem encountered with different viscosity values. Thank you for your time and considerations. Nuray |

Hello Nuray,
Perhaps the Pracht's method be very good. See the following paper: Pracht,W.E.,1971. A numerical method for calculating transient creep flows. J.Comp.Physics 7, 46-60. Good Luck for you. |
